Question:
If I start a java thread from the 搈ain?thread of execution and that thread I just created finish抯 executing its 搑un?method is that threads resources automatically clean up? Or do we have to do this clean up ourselves?
Is the under the hood thread stuff cleaned up or do we need to call the join method or some other method?

Depends which resources you mean. There's nothing special about threads in that respect.
Memory is automatically reclaimed when it is no longer reachable, so unless the run method set some member variables in some object that remains reachable after it completes, no worries there.
Files, sockets, etc. remain open unless you close them.

Probably.

Yes.
